How to exclude the weekends?
If you don't want to include your weekend in your calculation, you must use the function WORKDAY
The function WORKDAY needs 2 arguments.
- The first argument of the function is your Date
- The number of days to add
In our example, we simply have to write this formula to add days excluding the weekend
The function WORKDAY assumes that the weekend is Saturday and Sunday. But for some Arabic countries, the weekend is Thursday and Friday. If you work in this part of the world or if you work in these countries, it is important to calculate the weekend properly. In that case, you use the function WORKDAY.INTL
The first 2 parameters are the same as the function WORKDAY. But here, you have a third parameter where you specify which days are the weekends. So, in this case, you have to select the option 6.
Apply this to our worksheet and the following result is returned, appropriate for this region:
As you can see, for the same start date and an extra 1 day, the end date on row 4 is 3 days later due to the weekend falling on Thursday and Friday.
